The big draw of the day was an intimate performance by musician Dave Matthews – who played a myriad of old and new material for a small crowd – perhaps about 300 – though the event itself sold in the vicinity of 1700 tickets. Apatow and wife Mann are longtime fans of the cause.

Apatow has just finished his latest film, “This is 40” a quasi “sequel” to “Knocked Up.” The new movie follows Pete and Debbie (played by Paul Rudd and Ms. Mann), the bro-in-law and sister of the Katherine Heigl character from the earlier film. “It stars also Maude and Iris, my daughters, as well as Albert Brooks, Megan Fox, Jason Seigel, Robert Smiegel who is participating as an actor not a writer … it’s just finishing now in a few weeks. The studio wanted it for Christmas time, but I’m just happy to be relaxed and be done – now I can focus on how to get people to go see it.”

The new movie, unlike most Hollywood films, isn’t focused on tweens, teens and twentysomethings. “It’s all about how this couple can deal with life at 40,” says the filmmaker, who also directed “The 40 Year Old Virgin” and produced “Bridesmaids.

“How can you relate since you’re barely 35?” this WSJ writer chided the 44 year old.

“I’m just fantasizing about the future,” Apatow cracked.

During our tete a tete, Matthews joined the conversation, and he and Apatow talked kids (he has 10 year old twins and a 4 year old son). Matthews was not all about talking shop – he even stopped to pose with one 27 year old fan who said he had seen Matthews close to 40 times. Mann joins her husband and Matthews as someone yells to her, ‘Your husband is the bomb’ – to which Ms. Mann – who’s probably heard this 1000 times just smiled and responded “I know, right?”
